Driveaway SNG Antenna Range

Vehicle-Mounted Satellite Antenna Systems for Field Deployment

The DH range is built around carbon-fiber reflector construction, three motorized pointing axes and controller-assisted acquisition. The four aperture sizes share the same deployment concept but differ in RF performance, movement range, packaging, weight and environmental ratings.

Aperture Range1.2–2.4 m

Four vehicle-mounted reflector sizes allow the antenna package to be matched to link budget, roof space, payload and stowed-envelope constraints.

Published Ku Gain42.1–48.81 dBi

Published mid-band gain ranges from 42.1 dBi receive on the 1.2 m model to 48.81 dBi transmit on the 2.4 m model.

Pointing AxesAZ / EL / POL

Azimuth, elevation and polarization movement are motorized. Published travel and speed ranges differ by reflector size.

AcquisitionBeacon / DVB

The 1.2–1.8 m sheets list Beacon pointing/DVB acquisition. The 2.4 m sheet lists built-in DVB-S, DVB-S2 and CW beacon functions.

Configuration Accuracy

Confirm the Final Band and Feed Before Ordering

The published model sheets use different band labels. The RF tables for all four models show Ku-band linear values, while the feature lists and option headings identify additional feeds. The exact feed, polarization, interfaces and Rx/Tx frequencies should therefore be fixed in the quotation and approved drawing.

Published Band References

1.2 m: “Ka-Band Option” heading; Ku-band RF table; Ku and Ka feed systems listed.
1.5 m: “C-Band Option” heading; Ku-band RF table; Ku and Ka feed systems listed.
1.8 m: “C-Band Option” heading; Ku-band RF table; Ku and Ka feed systems listed.
2.4 m: L, C, X, Low Ku and Ka option ranges listed; Ku-band RF table published.

Engineering Confirmation

State the required receive and transmit frequency ranges, polarization, satellite service, feed interface, BUC/LNB arrangement and controller functions. Where a published source contains a formatting ambiguity—such as the 1.5 m transmit insertion-loss entry shown as “05”—the intended value should be confirmed in writing rather than assumed.

System Operation

From Vehicle Integration to Satellite Acquisition

A driveaway terminal is not selected by reflector diameter alone. Roof structure, RF chain, controller logic, power, cabling and operating environment must work as one system.

STEP 01

Check the Vehicle Envelope

Confirm mounting base, roof reinforcement, payload, cable routes, stowed dimensions and operating clearance.

STEP 02

Deploy the Reflector

The controller drives azimuth, elevation and polarization from the stowed position into the operating range.

STEP 03

Initialize Direction Data

Integral sensors support pointing. The 2.4 m sheet additionally lists GPS and an electronic compass.

STEP 04

Acquire the Satellite

Published modes include Beacon/DVB on the 1.2–1.8 m models and DVB-S, DVB-S2 and CW beacon functions on the 2.4 m model.

STEP 05

Verify the RF Link

Confirm signal peak, polarization, RF interfaces, BUC/LNB operation and the project-specific acceptance criteria.

The published 1.8 m G/T value is lower than the 1.2 and 1.5 m entries despite the larger aperture. It is reproduced as published and should be confirmed when the link budget depends on this figure.

Applications

Where a Driveaway Antenna Fits

These systems are intended for temporary or mobile satellite links where the antenna is transported on a vehicle, deployed at the operating location and pointed toward the selected satellite.

Temporary voice, video or data links when terrestrial infrastructure is unavailable or disrupted.

Remote Industrial Sites

Project communications for energy, mining, exploration and other operations outside dependable terrestrial coverage.

Government Field Operations

Project Configuration

Information Required for Antenna and Vehicle Integration

A complete inquiry should define both the satellite link and the mechanical installation. This prevents the reflector size, feed, controller or outdoor-unit arrangement from being selected in isolation.

Project Input	Required Detail
Satellite and service area	Satellite name or orbital position, target beam, operating region and service provider requirements.
Exact receive and transmit frequencies	Use exact frequency ranges rather than only C, X, Ku or Ka band labels.
Polarization and RF interfaces	Linear or circular polarization, feed arrangement, waveguide or coaxial interfaces and flange type.
Link-budget targets	Required EIRP, G/T, availability objective, modem waveform and permitted antenna size.
BUC, LNB and outdoor units	Model, quantity, weight, power, mounting position, interfaces and cable routing. Published system weights exclude the BUC.
Vehicle structure	Roof dimensions, payload, reinforcement, mounting points, stowed height, aerodynamic limits and operating clearance.
Electrical supply	AC110–230 V, 50/60 Hz is published. The 2.4 m controller is listed as a 2U cabinet with power consumption ≤2 kW.
Acquisition and control	Beacon, DVB, DVB-S/DVB-S2, CW beacon, manual control, auto-stow and project-specific interface requirements.
Environment	Operating wind, survival wind where stated, temperature, ingress class, humidity and site exposure.
Acceptance documents	Approved configuration, drawings, interface list, packing list and the agreed RF/mechanical test requirements.

Technical FAQ

Common Configuration Questions

01Are all frequency bands available on every reflector size?

No. The published RF tables show Ku-band values for all four sizes, but additional feed references differ by model. Confirm the final band, exact frequencies and feed interfaces in the quotation and approved drawing.

02Is a driveaway antenna the same as a flyaway antenna?

No. A driveaway antenna is integrated with a vehicle and deploys from the vehicle-mounted base. A flyaway antenna is transported in cases and assembled or deployed on a ground support at the operating location.

03Does auto acquisition mean continuous satellite tracking?

Not necessarily. These data sheets describe auto acquisition and pointing functions for a deployed terminal. Continuous tracking of moving LEO or MEO satellites is a different requirement and should not be assumed from the driveaway specifications.

04Are the BUC and LNB included in the published weights?

The published total weights are stated as “without BUC.” The 2.4 m packing list also does not identify a BUC or LNB as standard packed items. Confirm the outdoor RF equipment and mounting arrangement separately.

05Which model includes a published mounting drawing?

The current 2.4 m data sheet includes a mounting-base layout and a stowed/operating-envelope drawing. Vehicle integration should use the complete drawing and a structural review rather than the summary dimensions alone.

06What should be checked before final model selection?

At minimum: exact Rx/Tx frequencies, polarization, link budget, required gain and G/T, BUC/LNB arrangement, vehicle roof dimensions and payload, power supply, acquisition method, operating environment and the required acceptance documents.
